Ljubiša D. R. Kočinac, Feruz S. Aktamov, Adilbek A. Zaitov




In the main result of this paper we prove a version of the well-known open mapping theorem for weakly additive, order-preserving operators between ordered real vector spaces with an order unit. We also provide a few examples to illustrate obtained results.
